Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Live access to X posts for real-time events Less restrictive on edgy questions Fast inference on Grok-3 and up	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Writing quality trails Claude/ChatGPT Political bias debates Ecosystem is just X	Image generation is weak No native web search on all tiers	Not a general chatbot Answers can be shallow on complex topics
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
